New paper: a methane absorption line list with sub-MHz accuracy in the mid-infrared region

Our recent paper entitled "A methane line list with sub-MHz accuracy in the 1250 to 1380 cm−1 range from optical frequency comb Fourier transform spectroscopy" was just published in the Journal of Quantitative Spectroscopy and Radiative Transfer!

In this work, we reported a new experimental line list of the ν4 fundamental bands of 12CH4 and 13CH4 and two hot bands of 12CH4 obtained from line-by-line fitting to high-resolution spectra recorded using a Fourier transform spectrometer based on a MIR optical frequency comb.The MIR laser used in this experiment was our compact, fiber-based frequency comb at 7-9 μm, developed by our group.

The work was done in collaboration with Umeå University (Sweden) and CNRS/Université Bourgogne Franche-Comté (France).
